只用CSS 来做圆角矩形的技术很早就有了,但是在网页的设计过程中,我们通常用图片 实现圆角矩形效果。现在网上很多关于无图片实现css圆角矩形的方法,虽说巧妙,但是 代码冗长,难以做到简洁,所以我觉得很疑惑。
无图片实现css圆角矩形的原理很简单,就是用1px 的水平线条来堆叠出圆角。 网上找到一些css圆角矩形的代码,供大家参考一下
样式1:简洁型css圆角矩形
css代码:
.b1,.b2,.b3,.b4,.b1b,.b2b,.b3b,.b4b,.b{display:block;overflow:hidden;} .b1,.b2,.b3,.b1b,.b2b,.b3b{height:1px;} .b2,.b3,.b4,.b2b,.b3b,.b4b,.b{border-left:1px solid #999;border-right:1px solid #999;} .b1,.b1b{margin:0 5px;background:#999;} .b2,.b2b{margin:0 3px;border-width:2px;} .b3,.b3b{margin:0 2px;} .b4,.b4b{height:2px;margin:0 1px;} .d1{background:#F7F8F9;}
页面代码:
<div> <b class="b1"></b><b class="b2 d1"></b><b class="b3 d1"></b><b class="b4 d1"></b> <div class="b d1"> <font style="font-size:26px;color:red; margin:0px 10px;">简洁型css圆角矩形</font> </div> <b class="b4b d1"></b><b class="b3b d1"></b><b class="b2b d1"></b><b class="b1b"></b> </div>
样式2:3D效果css圆角矩形
css代码:
.raised{background:transparent;width:40%;} .raised h1,.raised p{margin:0 10px;} .raised h1{font-size:2em;color:#fff;} .raised p{padding-bottom:0.5em;} .raised .b1,.raised .b2,.raised .b3,.raised .b4,.raised .b1b,.raised .b2b,.raised .b3b,.raised .b4b{display:block;overflow:hidden;font-size:1px;} .raised .b1,.raised .b2,.raised .b3,.raised .b1b,.raised .b2b,.raised .b3b{height:1px;} .raised .b2{background:#ccc;border-left:1px solid #fff;border-right:1px solid #eee;} .raised .b3{background:#ccc;border-left:1px solid #fff;border-right:1px solid #ddd;} .raised .b4{background:#ccc;border-left:1px solid #fff;border-right:1px solid #aaa;} .raised .b4b{background:#ccc;border-left:1px solid #eee;border-right:1px solid #999;} .raised .b3b{background:#ccc;border-left:1px solid #ddd;border-right:1px solid #999;} .raised .b2b{background:#ccc;border-left:1px solid #aaa;border-right:1px solid #999;} .raised .b1{margin:0 5px;background:#fff;} .raised .b2, .raised .b2b{margin:0 3px;border-width:0 2px;} .raised .b3, .raised .b3b{margin:0 2px;} .raised .b4, .raised .b4b{height:2px; margin:0 1px;} .raised .b1b{margin:0 5px; background:#999;} .raised .boxcontent{display:block;background:#ccc;border-left:1px solid #fff;border-right:1px solid #999;}
页面代码:
<div class="raised"> <b class="b1"></b><b class="b2"></b><b class="b3"></b><b class="b4"></b> <div class="boxcontent"> <h1>3D圆角矩形</h1> </div> <b class="b4b"></b><b class="b3b"></b><b class="b2b"></b><b class="b1b"></b> </div>
样式3:略带菱形的css圆角矩形
